Recently, an add-on solution for real-time navigation
of percutaneous procedures outside the bore has been presented and clinically
deployed. The purpose of this work was to thoroughly evaluate the diagnostic
accuracy and workflow of 240 experimental biopsies by different operators.
The mean success rate (93%) and median biopsy time (3:58 min, including MR table
movements and control scan) observed for attending radiologists suggest that
an "in-and-out" approach does not necessarily compromise diagnostic
accuracy or clinical workflow. While the clinical performance can only be
assessed on patients, this work provides valuable results for a large number
of biopsies and different operators.
